在前期研究的钢渣最佳替换率的基础上,将不同粒径钢渣制成普通硅酸盐钢渣混凝土试块,分别浸泡在硫酸根离子浓度为8000 mg/L和镁离子浓度为3000 mg/L的侵蚀溶液中,分析在6个月侵蚀期内普通硅酸盐钢渣混凝土分别在侵蚀环境中的抗侵蚀性能。试验结果表明:钢渣粒径的大小对钢渣混凝土抗侵蚀性能是有影响的,钢渣粒径越小,其含有的游离活性成分越少,在其配制强度不降低反而增加的情况下,对其抗侵蚀性能有帮助。
On the basis of the optimal replacement rate of steel slag in the previous study, ordinary silicate steel slag concrete specimens with different particle sizes were prepared and immersed in sulfate ion concentration of 8000 mg / L and magnesium ion concentration of 3000 mg / L Corrosion solution of ordinary silicate steel slag concrete in erosion environment in 6 months erosion period respectively. The experimental results show that the size of steel slag affects the corrosion resistance of steel slag concrete. The smaller the steel slag particle size, the less free active ingredient it contains, Erosion performance helps.
